How do you convert feet per second to miles per hour?
1 mile = 5,280 feet. 1 hour = 3,600 seconds (60 seconds / minute * 60 minutes / hour) Therefore 1 mile / hour = 5,280 feet / 3,600 seconds = 1.47 feet / second. So to convert miles per hour to feet per second, multiply by 1.47. And to convert feet per second to miles per hour, divide by 1.47. So for example 110 feet per second = 110 / 1.47 mph = 75 mph. And if you had it the other way, you'd take 75 mph * 1.47 to get 110 feet per second. BTW, if you're trying to figure out how fast a 75 mph fastball gets to a hitter, first figure out that it travels 110 feet per second, and then divide 60.5 (the number of feet from the mound to homeplate) by 110 (the number of feet the ball would travel in one second) and get 0.55 seconds. So a 75 mph fastball takes just over half a second to reach the batter.
